1098s front fork on my M796

[chiu]

Hi,
I am going to purchase a 1098s Ohlins front fork for my M796. As i know the fork for 1098S is 53-56mm and my M796 is 50-54mm, so i am going to find someone to help me to wear down my triple tree clamp to fit the fork.
Anyone know apart from the diameter is different, any other parts i need to change to fit the 1098s fork on my M796?
Is the axle and nut the same?
All ducati brake calipers also are 100mm, right?
Do i also need to change the fender??
Thanks.

not sure you have enough material on your stock to fit the 56mm lower
plenty of people have bored the top for the 53.

probably would be better to purchase complete upper and lower triple kit. I replaced it with an Style and Performance set, others have used IMA and I think there are a few more options.

the axle and spacers are different, not 100% it's a different nut.
best to get the axle, nut and axle spacers (1 of your old ones and one of the SBK is what i used but can't tell you which)

the brake calipers are the 100mm mounts, but unless you use the 1098 330mm rotors you can throw away the 5mm spacers on from the forks if they come with it when you buy them.

you'll need to change some things for the rotors.
the 1098 have a 5mm per side larger offset
so you'll either have to
-get 5mm spacers with 5mm longer bolts to mount between your stock rotor and your stock wheel
-get 5mm more offset rotors with the 6-bolt mount (very rare and hard to source 748R/998R rotors only)
-get a sbk wheel and rotors

Fender should fit. I think only the gas charged works type fork is different, but I don't have the Ohlins.

thanks. More  questions come, i knew that the offset is not same, so i am going to purchase both stock upper and lower triple tree clamp. And i will wear down the trip tree clamp to 53m mand 56 mm. Is the offset still different if i use the stock triple tree clamp?
And i don't quiet understand the rotors part. Do i need to change the brake rotor. Any other method that i no need to change a new rotor?
Thanks.

not sure you understand the issue on the offset

i'm not talking about the offset of the triple

why are you purchasing new stock triples?

for the rotors they come in 3 types for different bikes
0mm offset for old monster
10mm offset for new monsters
15mm offset for superbikes

there are some threads in the how to as well as accesories and mods to search for with photos etc

seems so complicated for me. Any suggestion for me?

[Raux]

it's a bit complicated, but possible

[Raux]

ok. set a budget.

list of materials
Option 1: Low cost (key issue- can lowers be bored to 56mm?)
-forks
-5mm spacers for rotors and 5mm longer bolts
-axle, nut and spacers
-bore top triple (53mm) bored bottom triple (56mm)

Option 2: Mid-lower level (key issue sourcing brakes and boring issue)
-forks
-6-bolt, 15mm offset, 320mm rotors (@$300)
-axle, nut and spacers
-bore top triple (53mm) bored bottom triple (56mm)

Option 3: Mid-upper (key issue sourcing brakes)
-forks
-6-bolt, 15mm offset, 320mm rotors
-axle, nut and spacers
-New upper and lower custom monster triples for Ohlins fork ($300-$600)

Option 4: High
-forks (with 5mm caliper mount spacers if you use 330mm rotor)
-superbike rotors (320 or 330mm)
-superbike wheel
-axle, nut and spacers
-New upper and lower custom monster triples for Ohlins fork ($300-$600)

Option 5: lowest cost
-Monster 1100S Ohlins forks

If i choose the Mid-lower level, where can i buy the 6-bolt and spacer and how to make the 15mm offset??
My stock rotors is 320mm, so i don't need to change it, right?
Thanks.

you mean the low with the 5mm spacers for the rotors... check with motowheels i think... they also might have the bolts

[corey]

keep in mind the affects on geometry and safety that are involved here.
if you not sure you can tackle this properly, enlist the help of a pro.

[Raux]

honestly really think you should look at the M1100S forks if you can find em. directly swap

FYI  Motowheels does not carry the 5mm spacers. I checked this out when I did my fork swap. Motowheels will refer you to an Aprilia dealer in Texas called AF1 & they sell a 6 bolt rotor spacers that are only 2.5mm so you need 4 of these & it will cost you about $110.00 for 4. Just google Aprilia forum & that will get you to there web site/store

You can have spacers machined at a shop- sure to cost less than $110...

[chiu]

Any one know the upper and lower triple clamp of M796 is 50/54mm or 50/53mm?
Thanks.

I would advise grabbing a pair of calipers to check your measurements and parts you get before you have machine work done, install, buy parts, etc.
